What is the reason for the continuous flashing of the hazard warning lights?

[StMackenzie]

The hazard warning lights cannot be turned off, most likely due to a malfunction in the control box or abnormal wiring issues. In foggy weather, due to poor visibility, not only should the hazard warning lights be turned on, but also the fog lights should be activated to alert passing vehicles and provide illumination for oneself. In case of a malfunction or a traffic accident, when a vehicle breaks down or is involved in an accident on the road, the hazard warning lights should be turned on to alert passing vehicles to safety. On highways, if a vehicle breaks down or is involved in an accident and stops, failure to use the lights and set up warning signs as required will result in a 12-point penalty.
